At Cooklife, we understand that a true non-stick experience goes beyond just surface coatings. That’s why we’ve pioneered a unique surface Anti-Stick process, taking non-stick durability and performance to the next level. Our goal is simple: to provide cookware that maintains its anti-stick properties meal after meal, without the wear and tear typical of conventional non-stick coatings.
The Science Behind Cooklife’s Anti-Stick Process
Our advanced anti-stick process involves four steps to finish the cast iron cookware surface.
Firstly, the cookware is machined to keep a smooth surface. This process will remove the multi-hole surface of the original casting process, but still some grooves on the surface.
Secondly, a thermal-chemical treatment with nitrogen hardens the surface of our cookware at the molecular level. This technique, often utilized in high-demand industries such as aerospace and automotive manufacturing, creates a layer that’s remarkably resilient. The surface becomes not only tougher but also naturally fill in some surface grooves.
Thirdly, a prefabricated oxide layer is formed at high temperatures. The surface grooves are further filled in this step. Finally, the cookware will get well-seasoning before delivery. Seasoning is the process of coating the surface of cookware with vegetable oil which is heated in order to produce a corrosion resistant layer.
In the final step, the vegetable oil will fill all the grooves on the surface of cookware, and after the seasoning process there will form a dense and smooth anti-stick layer.
Unlike traditional non-stick coatings, which often rely on chemicals or coatings that can degrade over time, the anti-stick process deeply transforms the metal, embedding the non-stick properties within the cookware itself. This ensures that the surface remains durable and long-lasting, even with frequent use and high cooking temperatures.
What is Nitriding?
Nitriding is an advanced hardening technique originally used in high-performance fields like aerospace and automotive engineering. This process strengthens the cookware’s outer surface by introducing nitrogen into the metal, forming an ultra-durable layer of hard metallic nitrides. This layer, while extremely tough, remains just on the surface, leaving the inner metal more flexible—a combination that creates a resilient, long-lasting anti-stick effect.
Our nitriding process can produce a final surface hardness of up to 76 HRC (about 90 HRA), creating a strong outer layer with a typical depth of 200–300 microns (0.0002m). In some cases, this layer can be even thicker, reaching up to 2mm depending on the exact parameters we set. We control this depth and hardness by adjusting exposure time, temperature, and gas flow. For Cooklife cookware, nitriding typically occurs at temperatures between 500 and 550 °C (930–1022 °F) to ensure optimal durability.
This unique compound layer consists of a dense, white outer surface with a diffusion zone just beneath it, combining absorbed nitrogen and hard nitride precipitates. This structure is essential to creating cookware that not only resists sticking but also stands up to heavy use and high heat without wearing down.
How Cooklife Compares to Conventional Anti-Stick Technologies
Traditional non-stick cookware often uses PTFE (polytetrafluoroethylene) or ceramic coatings, which create a smooth surface but have limitations. Here’s how Cooklife’s anti-stick process stands out.
Durability
PTFE and ceramic coatings typically begin to wear down after a few months to a year, especially with frequent use. In contrast, Cooklife’s anti-stick surface is built to last, with anti-stick properties that endure without flaking or peeling.
High-Temperature Resistance
Traditional coatings may break down under high heat, leading to diminished anti-stick performance. The anti-stick process used by Cooklife is designed to withstand higher temperatures, maintaining a stable anti-stick surface without degradation.
Longevity
Many conventional non-stick pans need to be replaced due to wear on the surface. Cooklife’s anti-stick process creates a surface that stays resilient and effective over time, offering a much longer lifespan compared to typical coatings.
Cooklife: Anti-Stick Performance You Can Trust
Cooklife’s anti-stick process is a testament to our commitment to quality and performance. By moving beyond traditional coatings, we’ve created cookware that not only excels in non-stick performance but also stands the test of time. Whether you’re searing, sautéing, or simmering, Cooklife cookware is engineered to give you a hassle-free cooking experience, allowing you to cook with confidence and ease.
